Galaxy formation is regulated by the competition between gas accretion from the intergalalactic medium and supernova/AGN outflows. The circumgalactic medium is the interface that bears the signatures of both phenomena. Using state-of-the-art simulations, we have modelled metal enrichment by the first galaxies.

In this talk I will discuss the main outcome of our study, clarifying the interplay between galaxies and their surrounding environment. These predictions are compared to current observational data, allowing to draw key conclusions on the physics of galaxy formation and cosmic enrichment.
